        PCD Cutting Tool Blanks

        SF Diamond (SFD) manufactures a PCD cutting tool blank in diameter of 58mm. The performance and quality of this large-diameter cutting tool blank is equal in performance to the highest world-class standards.


        SF Diamond (SFD) manufactures a PCD cutting tool blank in diameter of 58mm. The performance and quality of this large-diameter cutting tool blank is equal in performance to the highest world-class standards.

        SFD not only has world-class production facilities for PCD cutting tool blanks, but also has advanced raw material inspection instruments (SEM), finished PCD testing equipment using ultrasonic scanning technology (C-SCAN), large-diameter PCD disc sintering capabilities, and proven PCD surface processing, polishing and cutting technologies.

        SF Diamond produces the widest selection of PCD cutting tool blanks in disc and cut-segment shapes for the precision tooling industry. There are 1μm, 2μm, 5μm, 10μm, 25μm, and mixed grain sizes available. In addition to grain sizes, the product options include polished or non-polished PCD surface, PCD layer thickness and carbide substrate thickness. We also offer nonstandard products on request. We offer technical literature and expert advice from our engineer team. By utilizing the correct grade you can control the surface finish necessary throughout the machining process and receive optimum tool life.

        SFD PCD cutting tool blanks are widely used for machining non-ferrous metals and alloys, such as aluminum, copper, aluminum/gray iron composites, as well as nonmetallic materials such as wood, chipboard, ceramics, plastic, rubber etc, where high abrasion resistance and good surface finish are required.

        SFD has been focusing on developing new PCD cutting tool blank grades which are suited to cutting and machining the variety of new and emerging materials in industry, and for tools targeted to meet our customers’ needs.



        SFD PCD cutting tool blanks are widely used in various industries:

        1. Woodworking industry

        SFD PCD cutting tool blanks fine micron series are suitable for processing solid wood, bamboo, plastic; middle grain sizes are good for universal applications for chipboard, wood composite, MDF, laminate flooring, etc.; The mixed microns and rough micron series are mainly for HPL veneer floor, PVC flooring board, MDF/HDF, and reinforced particle panels.

        2. Metalworking industry: Automobile,  etc.

        Many grades of SFD PCD cutting tool blanks are good for tooling various materials in automobile,  industries.

        Our sub-micron PCD is mainly for low Si content alloys to obtain perfect processing surface. The fine micron PCD series are for processing low Si content Al alloys, copper & copper alloys.The middle microns are mainly for <14% Si/Al alloys work pieces. The mixed microns and rough microns are good for tooling >14% Si/Al alloys work pieces, cast iron, carbide, CFRP, titanium and metal matrix composites, etc.

        3. Electronic industry (3C)

        SFD PCD products in medium fine grain sizes are also applicable for processing mobile phone frame, key, electronic circuit boards, etc., which require better surface finish.

        4. Building materials industry

        SFD PCD product in medium coarse grain sizes are also widely used for processing different materials in building & constructing industry, such as graphite, stone, carbon fiber composite materials, etc., which require higher wear resistance tools.



        1. Biggest R&D centre and strongest manufacturer of super hard materials in China..

        2. Wide PCD grain sizes from sub-micron to rough micron are available for all woodworking applications and metalworking applications.

        3. Very big production capability assures very fast deliveries of both whole PCD blanks and PCD cut tips
